How to get ready for WiMAX Design How-To 5/15/2008 Post a comment Are you looking for a comprehensive way to get up to speed on OFDM and MIMO? Here is some information on a new seminar, and some recent related articles that might help get you started.
Under the Hood: Mature devices get Rolly rocking Teardown 5/13/2008 Post a comment The Sony Rolly, shown at the Consumer Electronics Show in January, is a "dancing" MP3 player: When songs are loaded or streamed via Bluetooth, the Rolly can roll around and flap its speaker coverings in time with the music. The speaker flaps can also muffle the sound and give it a bit more flare when noise is channeled through one side or the other.
Top 3 considerations when selecting an antenna Design How-To 5/12/2008 2 comments In today's world where the smallest, thinnest and most versatile functioning mobile devices are ranked supreme, device manufacturers are finding themselves at a cross road where performance meets size and making the wrong antenna design tradeoff can have severe RF performance implications.
UWB chipmaker Artimi names new CEO News & Analysis 5/8/2008 Post a comment Artimi's Certified Wireless USB and high-speed Bluetooth connectivity products are integrated in PC peripherals, portable consumer electronic devices and mobile phones.
RF Puzzler: The Answer RF & Microwave Designline Blog 5/6/2008 1 comment Well done, a number of you identified this "Radio Frequency device" that was recently installed in my house.
Statistical Range Analysis in RF Systems: the "Range Fallacy" Design How-To 5/5/2008 2 comments You read every paper you could get your hands on to do with propagation and path loss at the frequency you're using, and you carefully included all the known (and measured) losses, antenna gains, power outputs and sensitivities in a detailed link budget. A few days later the marketing dept arrives at your office: "You said the range would be 5 meters but we tried it at that distance and we could make it fail." What has gone wrong?
60GHz: Achieving the ultimate wireless dream Design How-To 5/5/2008 Post a comment Using sophisticated design and fabrication techniques, research labs are getting closer to realizing 60GHz chips in silicon. When that happens, consumer price points can be met and wireless design becomes a whole new ballgame. But first, engineers must overcome five major challenges.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
